Ideally you should not ask that question. Just use the latest GCC (4.8 at the
time of this writing). And if you're asking which version is the minimum, it
stands to reason that you can upgrade. If you can, then just go for the
latest. There are decent Linux distributions for cross-compilation and
embedded devices, so you should consider one of them. I recommend taking a
look at Yocto.
Point in fact: if your toolchain comes with GCC 4.3, it's probably also got a
very old kernel, a very old glibc and other tools which are probably in need
of security updates.
PS: for Linux, the recommendation is "at most 3 years old". That would be 4.5
these days, though I'm sure 4.4 still works. 4.3 has not been tested in 5.x at
